The second company I found was Smartwool. I will say that I love their socks! They have a huge sock selection for men, women and children and many stores cary their brand, including Amazon, so they’re easily found. Make sure you check prices though as some stores have a huge mark-up on them!
We have tried both their T-shirts, pull-over and zip-up sweatshirts and they have all held up nicely. Make sure you follow the care instructions carefully by washing them in cold water and lay them out to dry so that they don’t shrink or get holes in them.
